Production of Lauric Acid and Pentaerythritol Based Biolubricant

Abstract

Production of a  biolubricant based on  lauric acid and pentaerythritol (PE) was carried out. The esterification reaction at 180°C-200°C for 6-7 hours in the present of sulphuric acid as catalyst. The  end product (PE ester) was confirmed through the determination of Fourier Transformation Infrared spectroscopy (FTIR), Nuclear Magnetic Resonance (NMR), GC-FID . The characterization of PE ester's of  viscosity index, pour point, flash point and  oxidative stability . The PE ester showed flash point at 250°C, pour point at 25°C, viscosity index 162 and the oxidative stability at 216°C respectively.The  PE ester produced is plausible to be used as potential  biolubricant.
